mrcz is a package designed to supplement the venerable MRC image file format with a highly efficient compressed variant, using the blosc meta-compressor library to shrink files on disk and greatly accelerate file input/output for the era of “Big Data” in electron and optical microscopy.
Python versions 2.7, 3.4-3.6 are supported.
mrcz is currently considered to be a beta development state.
mrcz is released under the BSD 3-clause license.
Installation
A scientific Python installation (such as Anaconda, WinPython, or Canopy) is advised. After installation of your Python environment, from a command prompt type:
pip install mrcz
mrcz has the following dependencies:
numpy
blosc (optionally, but highly recommended)
Feature List
Import: DM4, MRC, MRCZ formats
Export: MRC, MRCZ formats
Compress and bit-shuffle image stacks and volumes with blosc meta-compressor
Asynchronous read and write operations.
Support in the hyperspy electron microscopy package.
